Yes, I’m truly grateful for your invaluable assistance, as it has provided me with valuable insights on how to enhance the efficiency of my calculations.

[Bobbie]

Yeah, Mathias. I found that information in Section 10.9 (Lesson 9: Run your Programs on a Parallel Machine) of the User Guide. After adhering to the instructions to modify the config.mk file, it seems that parallel computation across multiple CPU cores has been successfully implemented without encountering any errors or warnings. Thank you once again for your assistance.

Hello,Adrian. Thank you for your answer. Given that my current computer is equipped with multiple CPU cores and threads, I’d like to leverage CPU parallel computation to accelerate the simulation process. May I inquire if this approach aligns with the MPI (Message Passing Interface) you mentioned, as I’m not very familiar with these concepts?

[Bobbie]

Although the code is running, the calculation process is very long. Is this related to the change of value of noofCuboids?

[Bobbie]

Hello，Adrian. This code is used to simulate the multi-phase flow inside a porous media, so I combined the codes of porous media (like resolvedRock3d) with the example of multiphase flow (FreeEnergy multi-phase model). And then the above issue occurred at running time.
But when I changed the noofCuboids to 1, the code seemed to work, but the terminal still displayed the above issue(no discreteNormal is found).

[Bobbie]

Thank you for your attention. I have reviewed the geometrical model in Paraview, and the details are clearly visible. However, I am unsure which step is causing the above issue.

Dear Jan,
Thank you for sharing your method with great respect! I’ll give it a try and I hope it will succeed.
Best wishes,
Bobbie

Dear Nipin(Nipinl)
You are quite right and the case you mentioned seems incomplete. I have also appeared problems when I tried to make and run it. I’m also trying to improve it, but I haven’t made much progress yet. Perhaps the answer Jan gave is feasible, but I haven’t had a chance to try it. You can try it. And do you have any new findings that I hope we can continue to communicate.
Best regards,
Bobbie

Thank you for your help again!

Thank you for your answers, Adrian. The geometric model was generated by SW and exported to stl format. The size of the model is 0.15 mm * 0.15 mm * 1 mm. So I followed the example and Users Guide to set the stl unit to 0.001 when importing the stl file,such as follows:

STLreader<T> stlReader( “multicylinder3d.stl”, converter.getConversionFactorLength(), 0.001 );
IndicatorLayer3D<T> extendedDomain( stlReader, converter.getConversionFactorLength() );

Should I adjust the value of 0.001 in above codes or make changes in other locations to prevent the occurrence of the aforementioned issues?

Thank you for your help again!
Best wishes!
